Based on the JEDEC standard JESD79-3F. The tRAS timings should include
the highest speed bins at a given frequency. This is similar to commit
683c67b ("mv_ddr: ddr3: fix tfaw timimg parameter") where the wrong

f402d268e8 fastboot: common: fix default fastboot_boot on 64-bit
When booting on a 64-bit system, the boot_addr_start buffer is not
large enough to contain a 64-bit number, thus leading to a crash
even if fastboot_buf_addr is valid, only the high part of the address
will be printed to boot_addr_start :

fastboot with fastboot_buf_addr = 0x0000000006000000:

With this fix, boot_addr_start can have the full 64-bit address passed

commit 801f1fa442 "dm: usb: udc: Use SEQ_ALIAS to index the USB gadget
ports" changed the way the udevice if found. It uses the alias to find
a udevice for a given USB port number. In the commit log it was stated
that if no alias is provided, the bind order will be used instead. However
it doesn't work. Fixing this by adding a call to uclass_get_device() if
uclass_get_device_by_seq() fails.

82fadccccf drivers: net: ldpaa_eth: check if the dpmac is enabled
some dpmacs in armv8a based freescale layerscape SOCs can be
configured via both serdes(sgmii, xfi, xlaui etc) bits and via
EC*_PMUX(rgmii) bits in RCW.
e.g. dpmac 17 and 18 in LX2160A can be configured as SGMII from
serdes bits and as RGMII via EC1_PMUX/EC2_PMUX bits
Now if a dpmac is enabled by serdes bits then it takes precedence
over EC*_PMUX bits. i.e. in LX2160A if we select serdes protocol
that configures dpmac17 as SGMII and set the EC1_PMUX as RGMII,
then the dpmac is SGMII and not RGMII.

Therefore, in fsl_rgmii_init function of SOC, we will check if the
dpmac is enabled or not? if it is (fsl_serdes_init has already enabled
the dpmac), then don't enable it.

d46d27d3b6 MTD: mxs_nand_spl: Redo the way nand_init initializes
Currently the spl system calls nand_init which does nothing.
It isn't until an attempt to load from NAND that it gets initialized.
Subsequent attempts to load just skip the initialization  because
NAND is already initialized.

This moves the contents of mxs_nand_init to nand_init.  In the event
of an error, it clears the number of nand chips found.  Any
attempts to use nand will check if there are nand chips available
instead of actually doing the initialization at that time. If there
are none, it will return an error to the higher level calls.

3eeb09b4c0 x86: Add efi runtime reset
Our selftest will soon test the actual runtime reset function rather than
the boot time one. For this, we need to ensure that the runtime version
actually succeeds on x86 to keep our travis tests work.

So this patch implements an x86 runtime reset function. It is missing
shutdown functionality today, but OSs usually implement that via ACPI
and this function does more than the stub from before, so it's at least
an improvement.

Eventually we will want to have full DM functionality in runtime services.
But this fixes a travis failure and doesn't clutter the code too heavily, so
we should pull it in without the amazing new RTS DM framework.

Replace the current rather convoluted code using ad-hoc polling
mechanism with a more straightforward code. Use wait_for_bit_le32()
to poll the DDRCALSTAT register instead of local reimplementation.
It makes no sense to pull for 5 seconds before giving up and trying
to restart the EMIF, so instead wait 500 mSec for the calibration to
complete and if this fails, restart the EMIF and try again. Perform
this 32 times instead of 3 times as the original code did.

Do the reset before clearing the MSR, otherwise it may result in a read
or write operation instead if the start condition is repeated.

bc00512438 i2c: i2c_cdns: Add support for handling arbitration lost
This patch adds support for handling arbitration lost
in case of multi master mode. When an arbitration lost
is detected, it retries for 10 times before failing.

006265d063 i2c: i2c_cdns: Fix clearing of all interrupts
The arbitration lost interrupt was not getting cleared
while clearing interrupts. This patch fixes this by adding
arbitration lost interrupt as well during clear. This patch
also removes hardcoded value and defined a macro for it.

a51cd54eff spi: Rename sun4i_spi.c into spi-sunxi.c
Now the same SPI controller driver is reusable in all Allwinner
SoC variants, so rename the existing sun4i_spi.c into spi-sunxi.c
which eventually look like a common sunxi driver.

Also update the function, variable, structure names in driver from
sun4i into sunxi.

853f4511e9 spi: sun4: Add A31 spi controller support
The usual SPI transmission protocol in Allwinner A10 and A31
controllers share similar context with minimal changes in register
offsets along with few additional register bits on A31.

So, add A31 spi controller support in existing sun4i_spi with A31
specific register offsets and bits.
